A study conducted by ESET Smart Home Research says that Amazon Echo Smart Speakers and Kindle E-Readers are vulnerable to Key Reinstallation Attacks (KRACK) where hackers can infiltrate the devices through Wi-Fi access points.
ESET researchers claim that the vulnerability can allow a man in the middle attack where they could view and start controlling the traffic across the Wi-Fi which offers standard WPA2.
Tens of millions of Echo & Kindle devices are already operating across the United States and the world and so the discovered flaw could spell a serious concern if we start believing what is being said by ESET Security Researchers.
Milos Cermak, the chief researcher at ESET disclosed that the flaw happened as the vendors did not develop the devices with deep security in mind.
However, Amazon has reacted to the issue and said that it has patched these vulnerabilities by issuing automated security updates as customer trust is extremely important to it.
Furthermore, the ESET researchers also found some vulnerabilities in Amazon Home Assistant. Dubbed as Broadcast Replay Attack, this kind of network vulnerability can be exploited by launching a DDoS attack say, experts. However, the same researchers say that the attack is not that easy to launch and so won’t apply to everyone.
NOTE- As the flaw was discovered and reported to Amazon last year, the technology giant issued a fix early this year. However, it is better to check the firmware of your respective device by going into the Kindle Settings or Echo App.
